It, therefore, had a higher rate of fire with little loss in hitting power. The British ordered more guns as secondary armament for HMS ''Furious'' and HMS ''Hood''. A total of 81 guns were made and were used on the following ships: HMS ''Chester'', HMS ''Birkenhead'', , , and HMS ''Hermes''. Guns removed from ''Chester'', ''Birkenhead'' and ''Furious'' were used to arm Armed Merchant cruisers: HMS ''Laurentic'' and HMS ''Montclare''.
